The construction of this special issue, focusing on measurement of intimate partner violence (IPV), was designed to raise questions and to point out potential limitations by which social scientists have approached measuring IPV. Research on IPV, consisting mostly of United States’ samples, is critiqued with the goal of expanding our conceptions of this phenomenon and energizing future research focused on measurement of IPV. This special issue contains a historical perspective of the measurement of IPV, addresses technical concerns of reliability and validity as they apply to IPV, considers unique aspects of assessment based on gender or same-sex relationships, contains a novel approach proposing assessment of interactional observation units, and proposes methodologies for assessment with different cultures. All contributors provide recommendations for improving the assessment of IPV.
